What does relief can be granted mean?

[sevenfortythree]

I have been looking up some lawsuits and found many motions to dismiss, and grants, for "fail[ing] to state a claim upon which relief can be granted". What does this mean?

I have tried to look it up and I keep getting other cases that have the same wording...but i cant seem to decipher what it actually means, or the extent.

It means the defendant tries to show the court that the plaintiff does
not have a "valid" claim (the plaintiff fails to state a claim upon which
relief can be granted) & defendant tries to get the case dismissed.

Some examples - there is no law to support plaintiff's claim; there is
an absence of facts sufficient to make a good claim; when some fact
disclosed in the complaint defeats plaintiff's claim/complaint.
